Simplify |3 − 11| + 4 × 2³. Can you explain this so I can understand how it works?

Answers

First start with the order of operations, PEMDAS, parenthesis, exponents, multiplication and division, and addition and subtraction. So, begin with simplifying |3-11|. 3-11= -8, but the absolute value signs tell you to use the absolute value of -8, which is 8. So now your problem is 8 + 4 × 2³. Next, simplify the exponent. 2³ is the same thing as 2 × 2, which equals 4. Now your problem says 8 + 4 × 4. The next step in the order of operations is multiplication and division, so simplify the multiplication in the problem, which is 4 × 4. This equals 8 so now the problem is 8 + 8 which equals 16. So, 16 is your answer.
